​Architect William Koelle's 1922 Sansom Gardens project was a concept. Instead of replacing the tiny, older houses on the back streets (in this case c. 1860 and built for the Irish servants working in the mansions across the brick path), families of the 1920's found charm in the narrow streets, small windows, and traditional forms. Rather than building new rows, the old houses were renovated, with tell-tale casement windows and Spanish stucco detail on Beechwood, Panama, Rittenhouse and the western blocks of Pine Streets. Koelle specialized in such adaptations for the cream of old Philadelphia society. The style of this house is Spanish colonial with french windows and iron balconies on the second floor, roundels over entrances and a barrel tiled roof. ​
